The biggest online threat to businesses and consumers today is ransomware, a category of malware that can encrypt your computer files until you pay a ransom to unlock them. With this practical book, you'll learn how easily ransomware infects your system and what steps you can take to stop the attack before it sets foot in the network. Security experts Allan Liska and Timothy Gallo explain how the success of these attacks has spawned not only several variants of ransomware, but also a litany of ever-changing ways they're delivered to targets. You'll learn pragmatic methods for responding quickly to a ransomware attack, as well as how to protect yourself from becoming infected in the first place. Learn how ransomware enters your system and encrypts your files Understand why ransomware use has grown, especially in recent years Examine the organizations behind ransomware and the victims they target Learn how wannabe hackers use Ransomware as a Service (RaaS) to launch campaigns Understand how ransom is paidand the pros and cons of paying Use methods to protect your organization's workstations and servers

This book constitutes the revised selected papers from the 11th International Conference on Risk and Security of Internet and Systems, CRISIS 2016, held in Roscoff, France, in September 2016. The 17 full papers presented in this volume were carefully reviewed and selected from 24 submissions. They cover diverse research themes, ranging from classic topics, such as intrusion detection, applied cryptography, formal methods and methodology for risk and security analysis, to emerging issues, such as ransomware and security of software defined networking or virtualization techniques.

Providing comprehensive coverage of cyberspace and cybersecurity, this textbook not only focuses on technologies but also explores human factors and organizational perspectives and emphasizes why asset identification should be the cornerstone of any information security strategy. Topics include addressing vulnerabilities, building a secure enterprise, blocking intrusions, ethical and legal issues, and business continuity. Updates include topics such as cyber risks in mobile telephony, steganography, cybersecurity as an added value, ransomware defense, review of recent cyber laws, new types of cybercrime, plus new chapters on digital currencies and encryption key management.

They may have heard of such attacks but are not aware of their various types, techniques, and business impact. What You Will Learn Delve into the various types, stages, and economics of digital extortion Understand the science behind different attacks Understand the gravity of and mechanics behind ransomware and prevent and mitigate data breaches and financial losses Use effective tools to defend against ransomware Analyze attacks, the money flow, and cyber insurance processes Learn the art of preventing digital extortion and securing confidential data Get an idea of the future of extortion tactics and how technological advances will affect their development In Detail More and more cyber threats keep emerging every day, affecting organizations across the board, targeting the entire spectrum of the Internet. Digital--or cyber--extortion so far has come across as the most serious of such threats as it seeks to profit from criminal activity, akin to blackmail. Such extortion has been rising exponentially in the digital age and has become a huge illegal money-making business, affecting users and organizations ranging from small businesses to large enterprises. This is an insightful study spelling out in detail the ways and means employed by cyber criminals in targeting various devices and the multiple dangers such malicious activity embodies. Here will be found an overview of methods employed to impact and infect computers, smartphones, servers, and the IoT for cyber extortion. Then, it will move on to specific subjects in more detail, covering attacks such as DDoS-based extortion, cryptoviruses, and ransomware. You will learn how to prevent such attacks and eliminate them if you are compromised. This book will help you become a pro at securing your data and preventing your organization from paying a hefty ransom. Style and approach This step-by-step guide will start with the fundamentals of digital or cyber extortion and the various techniques used by hackers to demand ransom from an organization. It also focuses on types of ransomware and how it can infect your computer, mobile, cloud, server, and IOT. This practical guide will also explain how you can eliminate such attacks by leveraging various open source/commercial tools.

Despite the increase of high-profile hacks, record-breaking data leaks, and ransomware attacks, many organizations don't have the budget to establish or outsource an information security (InfoSec) program, forcing them to learn on the job. For companies obliged to improvise, this pragmatic guide provides a security-101 handbook with steps, tools, processes, and ideas to help you drive maximum-security improvement at little or no cost. Each chapter in this book provides step-by-step instructions for dealing with a specific issue, including breaches and disasters, compliance, network infrastructure and password management, vulnerability scanning, and penetration testing, among others. Network engineers, system administrators, and security professionals will learn tools and techniques to help improve security in sensible, manageable chunks. Learn fundamentals of starting or redesigning an InfoSec program Create a base set of policies, standards, and procedures Plan and design incident response, disaster recovery, compliance, and physical security Bolster Microsoft and Unix systems, network infrastructure, and password management Use segmentation practices and designs to compartmentalize your network Explore automated process and tools for vulnerability management Securely develop code to reduce exploitable errors Understand basic penetration testing concepts through purple teaming Delve into IDS, IPS, SOC, logging, and monitoring

Learn how to detect and prevent the hacking of medical equipment at hospitals and healthcare facilities. A cyber-physical attack on building equipment pales in comparison to the damage a determined hacker can do if he/she gains access to a medical-grade network as a medical-grade network controls the diagnostic, treatment, and life support equipment on which lives depend. News reports inform us how hackers strike hospitals with ransomware that prevents staff from accessing patient records or scheduling appointments. Unfortunately, medical equipment also can be hacked and shut down remotely as a form of extortion. Criminal hackers will not ask for a $500 payment to unlock an MRI, PET or CT scan, or X-ray machinethey will ask for much more. Litigation is bound to follow and the resulting punitive awards will drive up hospital insurance costs and healthcare costs in general. This will undoubtedly result in increased regulations for hospitals and higher costs for compliance. Unless hospitals and other healthcare facilities take the steps necessary to secure their medical-grade networks, they will be targeted for cyber-physical attack, possibly with life-threatening consequences. Cybersecurity for Hospitals and Healthcare Facilities is a wake-up call explaining what hackers can do, why hackers would target a hospital, the way hackers research a target, ways hackers can gain access to a medical-grade network (cyber-attack vectors), and ways hackers hope to monetize their cyber-attack. By understanding and detecting the threats, you can take action nowbefore your hospital becomes the next victim. What You Will Learn: Determine how vulnerable hospital and healthcare building equipment is to cyber-physical attack Identify possible ways hackers can hack hospital and healthcare facility equipment Recognize the cyber-attack vectorsor paths by which a hacker or cracker can gain access to a computer, a medical-grade network server, or expensive medical equipment in order to deliver a payload or malicious outcome Detect and prevent man-in-the-middle or denial-of-service cyber-attacks Find and prevent hacking of the hospital database and hospital web application Who This Book Is For: Hospital administrators, healthcare professionals, hospital & healthcare facility engineers and building managers, hospital & healthcare facility IT professionals, and HIPAA professionals
